Nutrition Studies Of The Brindled Madtom, Noturus Miurus Jordan, Based On Stomach Content Analysis, Randall Stephen Madding

Masters Theses

Brindled madtoms and small channel catfish (140 mm or less) were examined to determine their food habits and the possibility of competition for food organisms between the two species when collected from the same area.

Two hundred twenty-three brindled madtoms were collected from Polecat Creek (study area I) 3 miles southwest of Ashmore, Coles County, Illinois. The study in Polecat Creek was conducted from July 10, 1967 to June 5, 1968, collections being made approximately every month. Two hundred forty-five brindled madtoms and 140 channel catfish were collected from the Embarras River (study area II) 2 miles south of Charleston, …

Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny

Masters Theses

Thirty-seven male Chelydra s. serpentina were collected from Illinois, Louisiana, Mississippi, Tennessee, and Wisconsin during months of activity from May, 1969 to June 1971. Carapace length for each specimen was measured, and testes and epididymides were dissected out, weighed, measured, fixed, and preserved in Baker's neutral formalin within seven days of capture. Paraffin sections were stained with hematoxylin and eosin. Frozen sections were stained with Sudan IV.

The spermatogenic cycle was similar to those of other Chelonians and reptiles exhibiting post-nuptial spermatogenesis. In Illinois spermatocytogenesis begins in late March or early April. Meiosis is evident throughout May and early June. …

Roasted Soybeans For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Richard Berns

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Soybeans contain about 18% fat. In the past it has been economical to process the soybeans into soybean meal. Soybean meal is the major protein supplement fed to swine. The recent development of new equipment to cook soybeans on the farm has resulted in a renewed interest in the use of cooked soybeans in swine rations. The objectives of the study reported here were to compare the performance of pigs fed whole soybean meal and to study the effects of whole soybeans on the carcasses produced.

A Study Of Diet Preference By Early Weaned Pigs, Larry Hauser, Richard C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1970

The trial reported here was designed to compare the single-stimulus method of palatability testing with the free-choice selection method and to determine the effects of partially delactosed whey, with and without sugar, on the gain and feed efficiency of early weaned pigs.

Review Of Research Of The Value Of High Moisture Corn For Growing And Finishing Swine, L. J. Kortan

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Work at South Dakota State University during the 10 year period 1942-1951 with soft corn for growing-finishing pigs showed that hogs are well adapted to utilize soft corn. In all six trials during this period, pigs fed soft corn showed a lower rate of gain per day than the pigs fed hard corn. However, when the soft corn was dried and fed, the pigs made practically the same rate of gain as the pigs fed hard corn. Compared on a dry matter basis, the value of soft corn was practically equal to hard corn for growing pigs. However, the pigs …

The Effect Of Gestation Energy Levels On Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Restricting energy on total feed intake has been accepted as a desirable management pract ice for gestating sows and gilts. The advantages are reduced feed costs during gestation and larger and stronger litters resulting from more proper nutrition of the gestating sow. The common practice of reducing total feed level quite of ten reduces daily intake of energy protein and many of the other nutrients required by the sow. The experiment reported herein is an attempt to establish minimum required levels of metabolize energy for gestating sows and gilts under both summer and winter conditions. These sows will be maintained …

Wheat In Swine Finishing Rations, J. W. Mccarty, R. C. Wahlstrom, A. E. Dittman

South Dakota Swine Field Day Proceedings and Research Reports, 1970

The objectives of the trial reported here were:
1. To compare the performance of pigs fed rations with the same proportions of grain and supplement but with the grain corn in one rations and wheat in another ration.
2. To assess the possible feeding value of wheat's greater protein content by use of an all wheat ration in which there was a lower level of supplemental protein.
3. To assess the value of lysine in wheat rations by the effition of lysine to the same ration as used for comparison 2 (above).

The Effect Of The Parasite Hymenolepis Diminuta On Iodine Economy In The Rat, David Gourdon Holmes

Theses and Dissertations

A balance of iodine within the rats is important for the maintenance of normal thyroid function. Because of Hymenolepis d[imi]nuta's affinity for certain nutrients, it may upset norma[l] iodine balance in the rat. To determine this, tapeworm-infected and non-infected rats were given 125Iodide orally and the percent uptake of iodide by the thyroid and the amount of radioac[tiv]ity in the tapeworms was determined. The percent distribution of the radio-iodinated compounds in the thyroid, tapeworms and feces was also determined. These procedures were repeated except 125Thyroxine was administered orally. There was a decrease in percent iod[id]e uptake by thyroids of tapeworm-infected …

The Effects Of Formaldehyde On The Frequency Of Reversion Of The White-Ivory Mutant Of Drosophila Melanogaster, Ruth Ellen D. Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is an analysis of the effects of formaldehyde, a chemical which is both recombinogenic and mutagenic, on white-ivory (wⁱ) a highly mutable allele of the white locus of Drosophila. Formaldehyde is shown to significantly increase the reversion frequency of wⁱ. The results of this investigation differ from earlier observations in three respects: (1) there is a positive correlation between RNA (ribonucleic acid) concentration and reversion frequency in the presence of formaldehyde, but reversion does not appear to be totally RNA dependent; (2) female germ cells are more sensitive than those of the male; …

Hereford And Holstein Steer Performance On High Grain Diets With And Without Corn Silage, Cyril Bruce Russell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A factorially designed experiment had 18 Hereford and 18 Holstein steers on individually fed, high-grain diets. One diet included 59% rolled barley, 30% CSF beet pulp, 5% protein, vitamin, mineral, and stilbestrol supplement, and 6% chopped hay and straw. The other diet had corn silage (11% air dry matter equivalent) substituted for the chopped roughage and 5% of the beet pulp. The Holsteins were heavier at the start, 752 lb. as compared to the Herefords 686 lb. average. The weight differential was maintained throughout the approximately 180-day trial. The Holstein's feed consumption and rate of gain, 23.4 and 2.71 lb. …

Growth Of Eimeria Alabamensis From Cattle In Vitro And The Changes In Fine Structure Associated With Schizogony, J. Robert Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monolayer primary cultures of cells from bovine embryonic intestine (BEint), kidney (BEK), spleen (BES), and thyroid (BET) and cell line cultures of embryonic bovine trachea ( EBTr) and synovium (BESy)as well as established cell line cultures of Madin-Darby bovine kidney (MDBK), human intestine (Int 407), and Syrian hamster kidney (BHK-21) were inoculated with freshly excysted sporozoites of Eimeria alabamensis and observed for 4 days. Sporozoites penetrated all cell types during the first 24 hours in culture. Numerous intracellular sporozoites, trophozoites, and binucleate schizonts were seen in all cell cultures except Int 407. The best development occurred in BES and MDBK …

The Evolution Of Parasitism Among Bees, George E. Bohart

Faculty Honor Lectures

Before discussing parasitic bees, I will present a rough outline of the biology of "ordinary" or non-parasitic bees. The superfamily Apoidea (bees) includes perhaps 25,000 or 30,000 species divided into nine families by recent authorities (Stephen, Bohart, Torchio, 1969) . A common biological thread holding this vast assemblage together is the provision by adults of pollen and nectar for their young. Only in the honey bees (the genus Apis which includes four species) are the larvae fed primarily on a different substance (a secretion of the pharyngeal glands) , and even this is derived from pollen and honey eaten by …

Growth In Weight Of Selected Organs, Tissues And Systems In The Pig, William J. Loeffel, Robert M. Koch

Nebraska Agricultural Experiment Station: Historical Research Bulletins

As a result of investigations at the Nebraska Agricultural Experiment Station in 1929, 1930 and 1931 to determine the effect of weight and degree of fatness of the pork carcass upon the quality and palatability of the meat, 40 pigs were slaughtered, five each at the approximate live weights of 70, 80, 90, 100, 115, 135, 160, and 180 kg. This corresponds to carcass weights ranging from 50 to 150 kg. The results of the meat investigations and feedlot data were reported elsewhere (Loeffel et al.,1943). This study reports data relative to the weight of selected tissues and organs, as …

Feeding Urea To Cattle, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

RUMINANTS normally obtain the protein they require by digestion of the organisms that inhabit the forestomach (rumen), not by direct digestion of the dietary protein they chew up and swallow.

The organisms break down the dietary protein and then rebuild proteins in the form of more organisms.

Rearing Orphan Kangaroos, G L. Ward

Journal of the Department of Agriculture, Western Australia, Series 4

LICENCES are required in Western Australia if certain kangaroos and all species of wallabies are kept in captivity, but orphaned young joeys often need care and hand feeding before they can be released to fend for themselves.

Rationing Standing Crops To Sheep, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

This experiment was done at Merredin Research Station to develop and test a method of rationing standing crops to sheep, and also to find whether rationing would reduce the sheep's water consumption.

The experiment involved 60 sheep on 12 one-acre plots of drought affected Gamenya wheat.

Surplus Cereal Crops For Sheep Feed, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

SINCE the introduction of wheat quotas many farmers have considered feeding unsaleable grain to sheep.

The three alternative methods of feeding this grain to sheep are

• as standing crops

• as grain supplements, fed in the paddock

• as grain plus hay, in a feedlot.

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley

Masters Theses & Specialist Projects

The effects of chemical additives on the fermentation pattern and subsequent feeding value of corn silage was investigated over a two year period. Corn plants harvested in August 1967 (Experiment I) were ensiled with no additive, 3.50 per cent area, or urea-mineral mix supplying an equal amount of urea. Those harvested in August 1968 (Experiment II) were ensiled with no additive, 0.50 per cent urea, or 0.75 per cent urea. The nutritive value of these silages was evaluated chemically and by lactation trials.

:he addition of urea alone, or in combination with minerals elevated the initial pH and buffered against …

Crop Rationing : A Useful Drought Feeding Technique, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

A TRIAL carried out during the 1969 drought demonstrated that rationing standing crop is a practical method of feeding it to sheep when feed is scarce.

Rationing will be mainly a drought feeding technique for that part of the crop which will definitely be used as sheep feed. Crop that may or may not be needed for sheep would normally be harvested and the grain kept as a contingency allowance.

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

Journal of the Department of Agriculture, Western Australia, Series 4

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

Supplementing Calves With Tallow : Results Of A Trial At Wokalup Research Station, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE removal of butterfat from milk by separation, reduces the energy content of the milk by about 50 per cent., and must slow the growth of calves unless extra energy is provided from some other source.

In the dairying districts of Western Australia, there has been considerable interest in recent years in the addition of homogenised tallow to skim milk to provide extra energy.

Good calves have been produced by this means.

Carrying Prime Lambs Through Summer, R J. Suiter

Journal of the Department of Agriculture, Western Australia, Series 4

The annual lamb glut in September- October has caused many farmers to show interest in feed lotting and other methods of carrying over prime lambs for a higher priced market.

Unfortunately however, little information has been available on the necessary techniques under Western Australian conditions.

This report presents the results of the first year of a trial being conducted at Chapman Research Station to examine some of the problems associated with carrying lambs through the summer for later marketing.

Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin

Journal of the Department of Agriculture, Western Australia, Series 4

THERE was a great deal of controversy throughout the summer of Western Australia's 1969-70 drought over the feeding of supplements other than grain to grazing sheep.

This report summarises some of the experiments carried out by this Department to investigate various artificial means of supplementing sheep grazing stubbles and dry summer pastures.

Further details of the experiments can be obtained by contacting the authors.

The results failed to demonstrate economic responses to urea supplements for grazing sheep.

The Feed Year Approach To Dairying, P T. Arkell

Journal of the Department of Agriculture, Western Australia, Series 4

Dairy cows have different food requirements at different times of the year.

Cows in peak production require much more food per day than dry cows. It is a waste of money to feed a dry cow more than it actually needs for maintenance.

Equally, it is uneconomic NOT to feed a producing cow enough to give maximum production.

1970 Nebraska Beef Cattle Report, J. L. Adams, E. F. Frolik, H. W. Ottoson, F. E. Eldridge

Nebraska Beef Cattle Reports

The use of high concentrate rations in finishing cattle has led to a rather high loss of livers due to abscesses.

The 1967 Statistical Summary of the Federal Meat Inspection Service of the USDA indicated the total number of cattle inspected was 27,859,980. Of these, 9.6% were condemned because of liver abscess. Considering the value of a liver to be about $3, the estimated loss to the industry because of condemnatIon due to abscess would be over $8 million annually.

The incidence of liver abscesses increases as the roughage level in a finishing ration decreases below 5% (Table I). The …
